Factors affecting results or interpretation
(i) Bacterial contamination, repeated freeze-thaw cycles or heat inactivation of the specimens may affect the absorbance values of the samples with consequent alteration of anti-HD levels.
(ii) Diagnosis of an infectious disease should not be established on the basis of a single test result. A precise diagnosis, in fact, should take into consideration the patient’s clinical history, symptomatology, as well as serological data
(iii) Reliable results are dependent on adequate specimen collection, transport and storage.
(iv) Failure to separate whole blood within 6 hours collection.
(v) Failure to label specimen with patient name, date of birth and precise identifier
(vi) Failure to fill in a consultation-request form, in particular clinical information and doctor to be notified of findings.
